Which Renaissance painter made the 1474 portrait known as the Duke of Urbino?

Piero della Francesca made the 1474 portrait known as the Duke of Urbino.

The double portrait shows Federico da Montefeltro, duke of Urbino, and his wife Battista Sforza in profile. Piero painted the pair around 1473–1474, and the work is now in the Uffizi Gallery in Florence.

Federico's profile reflects the conventions of commemorative portraiture, while the reverse panels present allegorical triumphs of the couple. The landscape in the background also demonstrates Piero's interest in geometry, light, and carefully ordered space.

The work is often called the Diptych of Federico da Montefeltro and Battista Sforza. Battista died in 1472, so her portrait may have been completed posthumously, a point frequently noted in discussions of the diptych.
